Some vim adjustments
Backend support for Java
Missing case in Idris.Parser

This module:




    module main




    using (A : Type) 
      data W : Type where
        Ok : (r : A -> A -> Type) -> W




gave the error 




    src/Idris/Parser.hs:(215,23)-(223,86): Non-exhaustive patterns in case
    
which seemed to be repaired by this amendment for the [] case.

Missing case in Idris.Parser

Fix comedy error in termination checker
Only use metavariables as completions for :p and :prove
Stop completion of names that are prefixes of others

Previously, when completing "plus", it was accepted. Now, it tries completing
with "plusAssociative", "plusCommutative", etc, and the user has to press
space.
